Shock eliminator

Abstract

This invention provides an improved shock eliminator, particularly a shock eliminator for use in constructions such as bridges and houses. The shock eliminator includes a base, a carrier seat, a slide block and springs. The top side of the base is provided with a round curved concave slide recess. The slide block has a bottom surface formed with a curved surface equivalent to the slide recess in diameter and disposed in the slide recess, and a top side centrally provided with a hemispherical depressed coupling groove. The carrier seat is a plate member disposed on the top portion of the slide block and has a bottom portion centrally provided with a coupling post having a hemispherical distal end equivalent to the depressed surface of the coupling groove in diameter. The coupling post is disposed in the coupling groove of the slide block. A suitable number of springs are disposed on the surface of the slide block around the coupling groove to hook the bottom side of the carrier seat. The shock eliminator is installed at the bottom of a column of a building or bridge to ensure shock eliminating effect and safety of the building and bridge.

I claim:  
     
       1. An improved shock eliminator, comprising a base, a carrier seat, a slide block and springs, said base having a top side centrally formed with a round curved concave slide recess, said slide block being disposed in said slide recess and having a bottom side formed with a curved surface which has a diameter equivalent to that of said slide recess, and a top side centrally formed with a hemispherical depressed coupling groove, said carrier seat being a plate member disposed on the top portion of said slide block and having a bottom side centrally formed with a coupling post having a hemispherical distal end with a diameter equivalent to that of said hemispherical depressed coupling groove for insertion into said coupling groove of said slide block, a suitable number of said springs being arranged on the top side and the flank side of said slide block around said coupling groove such that one end of said springs being connected to the top side and the flank side of said slide block while the other end is connected to the bottom side of said carrier seat. 
     
     
       2. The improved shock eliminator as claimed in  claim 1 , wherein said base and said carrier seat are configured to have similar or different shapes and can be round, rectangular, square, elliptical or polygonal. 
     
     
       3. The improved shock eliminator as claimed in  claim 1  or  2 , wherein said carrier seat has a surface area equivalent, smaller or larger than that of said base. 
     
     
       4. The improved shock eliminator as claimed in  claim 1 , wherein said slide block has a cross section that can be round, square, rectangular, elliptical or polygonal. 
     
     
       5. The improved shock eliminator as claimed in  claim 1 , wherein said springs can be devices providing a damping effect or rubber-like materials. 
     
     
       6. The improved shock eliminator as claimed in  claim 1 , wherein said base and said carrier seat can be directly and tightly coupled. 
     
     
       7. The improved shock eliminator as claimed in  claim 1 , wherein said coupling post is hemispherical. 
     
     
       8. The improved shock eliminator as claimed in  claim 1 , wherein said base can be coupled with a rubber supporting pad or spring. 
     
     
       9. The improved shock eliminator as claimed in  claim 1 , wherein said carrier seat can be coupled with a rubber supporting pad or spring. 
     
     
       10. The improved shock eliminator as claimed in claims  8  or  9 , wherein said rubber supporting pad or spring can be a laminated-rubber bearing or lead-rubber bearing. 
     
     
       11. The improved shock eliminator as claimed in  claim 1 , wherein said base, said carrier seat and said slide block can be turned upside down. 
     
     
       12. The improved shock eliminator as claimed in  claim 1 , wherein positions of said coupling groove and said coupling post can be switched to have said coupling groove located at the center of the bottom side of said carrier seat and said coupling post located at the center of the top side of said slide block. 
     
     
       13. The improved shock eliminator as claimed in  claim 1 , wherein the surface of said slide recess is coated with durable lubricating materials. 
     
     
       14. The improved shock eliminator as claimed in  claim 1 , wherein the surface of said curved surface of said slide block is coated with durable lubricating materials. 
     
     
       15. The improved shock eliminator as claimed in  claim 1 , wherein the surface of said coupling groove is coated with durable lubricating materials. 
     
     
       16. The improved shock eliminator as claimed in  claim 1 , wherein the surface of said coupling post is coated with durable lubricating materials. 
     
     
       17. The improved shock eliminator as claimed in  claim 1 , wherein said coupling groove can be a cylindrical depressed hole with a hemispherical distal end.
